Continuity mistake: In the end when the Kothoga is on fire and chasing Margo, it catches up to her in moments. However, everytime it dramatically changes angles, the Kothoga appears alot futher away than it was previously, but soon after catching up once again. Noting her progress in the room, this situation is NOT simply replaying the same scene from different angles. Plus when she gets to the water tank, she has plenty of time to spare to hit a lever, climb the device, and jump in before the Kothoga looms overhead.
Plot hole: What happened to the two boys who stayed in the museum past closing, after the homeless guy seemed to attack (or at least be seen to be stalking) them? The next time we see them, it's the next morning, and they're fine. So where did they go? Who helped them? What happened to the homeless guy? The boys couldn't have just hidden, as the homeless guy has been in the museum for ages, and these two boys just got there that day. The homeless guy would have known all the nooks and crannies and every little hiding spot available; he would have caught them.
Trivia: Producers Gale Anne Hurd and Sam Mercer wanted to film the movie at the American Museum of Natural History in New York. However, the museum's administration was afraid that the film would not only cast the museum in an unflattering light, but it would also scare kids away from the museum. They were given permission by the Field Museum of Natural History in Chicago to film there, because they loved the movie's premise.
Question: Why was the relic being shipped to the Field Museum in Chicago via boat? What would be the point of sending the relic to the United States and then placing it on a boat and shipping it to Chicago by way of the Illinois River? In the book, the museum is instead located in New York, so it makes sense for the shipment to arrive by boat from South America, but there would be no possible way to get to Chicago straight from South America by boat, so the relic had to have been on land at one point. Placing it on a boat just seems like a contrived way to have the monster kill the crew members and create a mystery for the police as to how it happened.Serious B
